To allwkoa'n it may concern it: known th'at I, RoY. C; SHoWALTE'R, acitizen of the United States, residing at-Altoona; 111- the'count-y ofBlair and State of Pennsylvania, have invented new an'd usefulprovements in Signals, of which the fol- "lowlng 1s -a specificat ion. p

The invention contemplates improvements in signals and hasparticularreference; to' signals for indicating'the positions of switch,points in railroad track-structures.

One. of the objects of the present invention a is to provide a.signaling system ofthis character which shall inelilde a semaphore theas signaling arms of which are connected with a plurality of la pswhereby in the signal ing .positionoft elarr'ns the lamps may beilluminated to clearly-define the positions of the arms;

gresses, the invention consists of the features of construction,combination and arran- 'ement of parts hereinattter fully describedand-claimedfi In: the accompanying drawings forming a part of thisspecificationz -liighre l, is a perspective view of a signaling systemconstructed in accordance with the present in venticn. Fig 2 is a, sideelevation of a 40 nisml Fig. 3 is a d'etail yiew of the lamp switch.Fig. his a'detail'view showing the connection between 'the I signaling"arm and the switch. v. I 1

Similar reference characters designate 'like parts throughoutthe'several views. 4 Referring more partlcnlarly to the ac-! companyingdrawings.,- wherein I have illustrated the preferred embodiment, of theinvention, A d'esignates a rallroad .t-rack structuretatfove which ismol nted the sig naling brid e B provided with the usual semaphore 5which latter includes the varicoloredsignaling armslw 2 and .3. A6113-cent the semaphore C and rearwardl-y of the which shall appear as thedescription'prosemaphore arm and its operating mocha which are mountedthe switches D having ,operative connections with .thearms ofv tli'esemaphore as will be'here'in'att'er more fully describegil i Adjacentthe trackstr'uctnre A. is a hol,- low standard 5 having secured to itsupper end alamp support-'6 in which are mounted the electric lamps ,7',8 and 9, the-latter besi'gnalingarms of the semaphore'by means ofconductors '10 and the switches'D.

The'nume'ral ll-designates the main feed wires to which are connected,in parallehthe switches underjthe action of the signaling :arms thelamps may be illuminated to warn -the engineer of an approaching trainof the position of the arms. Each switch D conr- Cured to'the-standard 4having 'a flanged outer end 13 to which .is'bolted the flanged 'cnd' l'l of ,a removable cover 15, the cover being-secured to the housing by:means. of bolts 16 passing through alining openings 30 in the flanges!The cover is provided with a slot 17, the purpose of whith will apbottomof the casing 12, are spacedqiarall'el. cars 18 between which ispivotally mounted 5' :3; switchilever 1 9,provi'ded with an opera t' inghandle 20 and designed to engage spaced contact strips 21 forti ieduponthe interior of the hOusing'liZ and'in advance of the ears to closethe circuit to the lamp in the on operation of the arm. "Rigidlysecured-to the rear end of each signaling arm .isa yoke 22 provided witha rearwardl v projecting post 23 adapted to he connect-ed to one member24 of an 95 actuating mechanism E, through the medium of as-socket '23.Thelopposite member of the actuating mechanism E is designated at 25 andhas its lonerfiend pivotally the s'witch. 1.9.

The open end of thecylinder 26 is closed by a removable cap 28 formed with a centrallyarranged aperture 29 through which operates the member 24.

The lamps 7, 8 and 9 are preferably in the form of arc lamps, and eachis provided with a reflector to direct the light toward an approachingengine, whereby to indicate to an engineer, through thec'olor of lampburning, the desired signal.

In practice; the signaling arms are coni nected with the'switch pointsin any suitable manner so that in the movement of a switch, the arms maybe operated to indicate the position of such switch. For the sake ofillustration we will assumethat the arm 1 is moving in a downwarddirection. In downward movement, it will be seen that the arm 1 willelevate'the member 24 of the actuating mechanism E independently of themember 25, incident to the relative dimensions of the plunger 27 and thecylinder 26. Immediately preceding the arm 1 reaching the limit of itsdownward movement, the plunger 27 engages the'cap 28 of the cylinder 26and imparts upward movement to the member 25, which latter through itsconnection with the operating handle 20 and switch 19,- disengages saidswitch from the contact members 2l,-thereby' breaking the circuit to thelamp. When the arm 1 is thrown in an upward direction, under the actionof the switch. it is seen that the above operation is reversed, justbefore the arm reaches its limit of upward.

movement, the plunger 27 of the member 24engages the bottom of thecylinder 26 and consequently moves themember 25 in a downward directionwhereby the switch 19 is engaged with ,thecontact members 21 to permitthe flow of current to the lamp.

From the above description, taken in connection with theaccompanylngdrawings, it will be seen that I have provided a signalingsystem, in which the condition of the lamps remains undisturbed in themovement of the signal arms, but are rendered operative or inoperativeupon the arms'reaching their limit of movement in an upward or downwarddirection. a v

Having described the invention, what I claim and desire to secure byLetters Patent 1s:

1." A signaling systempcomprising 'a'semaa phore, a lamp, aswitchboxhaving a switcn therein, a switch actuating mechamsm pivotally connectedto said switch, said mechanism comprising a lower member havin acylinder at its free end, an upper member slldable in said cylinder,means carried by said upper member for limiting the movementthereof insaid cylinder, and means its arms slidable in said cylinder, meanscarried byv said upper member for limiting "the movement thereof insaid'cylindcr, the

an L-shaped upper member having one of other arm of said member beingprovided with an elongated slot, and means engaging said slot andconnected to said semaphore whereby said lamp is illuminated when saidsemaphore has reached the limit of its upward movement.

3. A signaling system comprising a semaphore, a lamp, a switch boxhaving a switch therein, conducting means between said switch box andsaid lamp, a switch actuating mechanism pivotally connected to saidswitch, said mechanism comprising a lower member having a cylinder atits free end, an L-shaped upper member having one of its arms slidablein said cylinder, the other arm of'said member'being provided with anelongated slot, means engaging said slot and connected to said semaphorewhereby said lamp is illuminated when said semaphore has reached thelimit of its upward movement, and means carried by the lower der wherebysaid switch'will be drawn in l and out of contact.
